What happens in transition zone?
The mantle transition zone (TZ) is the layer between two discontinuities in seismic wave-speed that lie at depths of approximately 410 km and 650 km [Anderson, 1989]. These discontinuities are polymorphic phase changes, caused by pressure-induced changes of crystal structure in certain minerals [Anderson, 1967].
Where is the transition zone?

The transition zone is part of the Earth’s mantle, and is located between the lower mantle and the upper mantle, between a depth of 410 and 660 km (250 to 400 mi). The Earth’s mantle, including the transition zone, consists primarily of peridotite, an ultramafic igneous rock.

Parts of the Nile River also pass through the zone. The environment of the African Transition Zone is known as the Sahel, a semi-arid region of grasslands created by the collision of the Sahara Desert and central African rain forests.
What river flows through the transition zone?
What does natural transition mean explain?
Explanation: A natural transition is a transition that is achieved using elements of the scene while recording, rather than adding an artificial transition in post-production. There are many ways to create natural wipes, dissolves and other effects — you are only limited by your creativity.
Why is it called the transition zone?
A transition zone is a physical area in which the land undergoes a radical change such as from arid to tropical.
What religions can be found in the transition zone?
Islam is the dominant religion on the north side of the African Transition Zone; Christianity is more dominant to the south. The two religions often clash in the areas where they meet. Traditional beliefs and animist religions are also practiced in the African Transition Zone.
Why is North Africa separated?
North Africa is separated from Subsaharan Africa by the African Transition Zone, a transitional area between Islamic-dominated North Africa and animist- and Christian-dominated Subsaharan Africa. It is also a transition between the Sahara Desert and the tropical type A climates of Africa’s equatorial region.
